near term now through Tuesday ... Surface high pressure remains in
control of the weather during the near term period, but a dry,
reinforcing frontal boundary dropping south across central al this
afternoon will drift south across our forecast area tonight. Lowest
levels of the atmosphere remain very dry through Tuesday, so no
rainfall is expected in association with the frontal passage. Aloft,
broken to ocnly overcast mid to high level clouds will continue to
stream east across the area through tonight, but all models are
indicating a break in the cloud cover on Tuesday, so will look for
more sunshine on Tuesday than past several days. Lows tonight
ranging from the upper 30s over northern interior zones, and in the
low to mid 40s further south with the warmest temperatures along the
coast. Highs on Tuesday will be in the low to mid 60s across the
entire area. 12 ds
short term Tuesday night through Thursday night ... High pressure
over the area will slide east through midweek, maintaining dry
conditions through much of the period. Meanwhile, a potent
shortwave will dive southeast and move across the southeast
Wednesday night. A brief return flow is expected in advance of the
shortwave on Wednesday with increasing clouds. However,
precipitable water values remain well below an inch and only an
isolated shower is expected. Temps will be in the mid and upper
60s on Wednesday followed by upper 60s to near 70 on Thursday.

13
long term Friday through Monday ... High pressure builds into
the area in the wake of the passing shortwave with upper ridging
also building over the area through the end of the week. This will
maintain dry conditions through Saturday with highs in the low to
mid 70s. Increasing clouds along with scattered showers with a
slight chance of thunderstorms will return on Sunday into Monday
as the upper level ridge advances eastward, low level return flow
sets up on a the backside of the exiting surface high pressure,
and upper level impulses traverse the forecast area. 13
marine... Surface high pressure over the plains will shift east
through the week, bringing a primary northeast wind flow through mid
week. A weak cold front will reinforce the offshore flow tonight,
and a small craft advisory is in effect for the offshore gulf waters
from late this afternoon through tonight. Elsewhere across the
marine area, small craft should exercise caution through tonight.

Winds and seas will subside slightly late in the week, gradually
becoming more east to southeast by the weekend. 12 ds

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
